IMPROVED SELF-SEALING BURIAL-GASE.

TO- ALL WHOM IT MAY CONCERN:

Be it known tlml: I, PETER F. LAWSIIE; of Rochester, 'in tl12e"county of' Olmstead, and State-of Minfiesota; have invented certain ne\ v und useful Impro'vemeqt sliqllieballic Burlal-Gases; and I do"hkergby declaria thai; the, folloying is zi. full, blear, ancl exact (lgsbripti 0nthereof, reference being ha 1d to the a00ompanying drawings, making art of this spedification, und t the leitersof reference markecl thereon, like letters -indicatihg like parts wherevx they occur.

lTo en'able otherdskilled in the urt to construct :xnd use my invention,I will prcecd to desribe it.

My invention consists lncerl:ain lmprovements ixlmetallic burial-cases, wheteby theyare renclered more perf'ecl: antlconenient'for lise, as hereinafter explainecl.

Figuro 1 is side elevation, with aportion broken away to' exhibit the packing.

- Fignre2 i s a transverpe section.

-Inj constructing metallic burial-cases, as heretofore used, it; has begn l;he cust0m to packtl 1em or render tl1cm aii-tlght by means f cement, cf one kind o1 zm other, an'd frqiiently it ls desirable, in f ;he removal cf bodies, td open anrl close tl1'e Gase, wlxere no cemeril: or other suitable material 1's at band 150 01036 il: air-tight especia-lly in the removal of bodies from battle-fielcls und similar places.

- My improvement consisfs in so const-rncting tl1e case, :md providing it wlth packing, tbat 'it-ma-y be used anywhere, ab any time, und be renclered self-sealing by th e simple ach of closing it.

Iconstruct my lmproved case in two arts, an upper and a. lower one, asirsual. The lo\\ei pn1t I provide with a laterally-projecting flange, a, in the upper fa0e of which I fo'rm a. Phanmel o1 grobve, as repres ented in fig. 2, a.nd in this groove I fit snugly a. strip of rubber, asrepresented by e: Gare should be.take'n to ha.ve this mbbe'r strip continuous, whicl1 ma y be done by forming it in one confiifiuos piec %,likea ring; r by unlting und cementing its encls When cut of the proper length to fit (alle gmo.o y, It may be inserted snngly in the groove without ceinenting il: therein; but I prefer to secur'e il: thereinby meansof rubber cement.

The upper part of the enge I construct with a fiange, whicl1 also projeotsrdially, a-nd h'as' a lip at its outer cdge t0 shut down over th edge of tl1e flange of t-he otl1er part, as shown -i n llg2.

I1; will thus be seen tlmt when tl1e two part s are playced together, as mpresented-in the drawing, tl1e rubber will Form a packing for tho joint tl1at will render tl1 e cnse. sg lf-Sealing, apd that Wl1en tl1usmacle, th case Gar. be usc(l in any pluce und at any time wit hout th o use of any cement specially provirled for the purpose; and further, that lt can be opened ancl closed as offen as required witl1out a.flecting tlie p'acking, 01 the ncssity of providing cement for sealing it again when once: openecl. All tlml: is roquireol issimply 60 screw the cdver doWn tight, und lt is sedlecl 01' renclered air-tight by tha.t simple operation.

It is bbvious that, instead of making the groove fov the rubbe1 ii1 one flange only, it may be runde partly in each, or that it may be dispiensecl with entirely, and the rubbersimply pluced between the two flanges; but I prefer, in -any case, to set tho rubber on edge, a il; is more certain to pack andsea.l the joint perfectly.

Having th'us clescribed my invention, whal c]aim is 1. A self-saling burial-case, constructed und arranged to operate substantially as clescribed.

2. A metallic burial-caseconstructed substantially as herein described, an provided with the ruliber packing, as und for Ehe purpose sei: fortl1.
